Finally I have saved enough dollars to have a lens upgrade. I've been always using my kit lens that comes with my 350D and it have serve me well. However I have some problems with taking pictures in low light conditions and also lack the zoom power on the tele end. I come to know that two good general purpose lens from tarmon and sigma which have an opening of F2.8. Tamron, SP AF28-75mm F/2.8 XR Di LD Aspherical (IF) and Sigma, 24-70mm F2.8 EX DG. Both generally recieve good reviews and now I and stuck with making a choice between both. I know this questions have been posted a zillion times. But I need some expert advise on this matter to maximise my dollar spent. Also it will be enlightening to know how to select a sharp version of the lens.
Your advise is greatly valued. Thanks
